To all whom) it may concern: 1

Be it known that l, W'Inminr S. it.

Tnnosn, a citizen of the United States, residing at Carlisle, in thecounty of Cumberland and State of Pennsylvania, have invented a new anduseful Improvement in Grain-Drills,ot which the following is aspecification.

. This invention relates to certain new and useful improvements in graindrills, and more particularly to the boot, the object be ing to providea boot which is provided with deflectors for scattering the grain so asto prevent the same from becoming hunched in the furrow, so that alldifficulties now existing with devices of this character will beovercome- Another object of my invention is to provide a boot with ashovel of a greater width than shovels now employed so as to form awider furrow to receive the scattered grain.

Another object of my invention is to provide a pressing roller inconnection with the boot, whereby the furrow will be closed and the soilpressed over the same.

Another object of my invention is to provide a grain tube with adeflector at its lower end in order to scatter the grain into the boot.

With these objects in view, the invention consists in the novel featuresof construction', combination and arrangement of parts, hereinafterfully described and pointed out in the claims.

In the drawing forming a part of this specification-:-Figure 1 is a sideelevation of my improved drill boot. Fig. 2 is a longitudinal sectionthrough the boot on the line of Fig. 3, a roller being shown inelevation. Fig. 3 is a reare levation. Fig.

I 4 is a section taken on line d d of Fig. 2.

Fig. 5 is an enlarged detail section on the line 4-4 of Fi 2. Fig. 6 isa section taken on line 6--6 0 Fig.5, and Fig. 7 is a plan view of theblank from which the deflector is, formed.

In carrying out my improved invention, I employ a metal boot A which isformed with apertured lugs'A at its forward end for connecting the sameto the drag-bar of the planter not shown. Secured to the front of theboot at its lower end is a shovel B which is fastened thereto by screwsthat: extend through the boot into the deflectors I) and E, thedeflector I) being semi-spherical in order to scatter the grain withinthe boot, and the deflector E which. IS arranged at the lower end isalso rounded so that grain passing down the boot will strike the sameand he spread outwardly to each side. Secured to the inside of the bootopposite the deflector E is a deflector.

I so that the grain passing down thGIefll wall of the boot will also hes read outwardly to each side, and said dbflector'is secured therein bya screw F which-also holds a plate G in position on the boot, said platebeing secured adjacent its upper end by an additional screw, so that thesame will be fastened thereto.

The plate Gr is provided with an apertured lug G at its upper endthrough which extends a bolt H on which is ivotally mounted the upperends of the rame I. The frame I carries a pressing roller J at its lowerend which is journaled on a bolt J extending transversely through theside bars of the frame, said roller is adapted to travel in the rear ofthe'boot in such a manner that the soil will be forced back into thefurrow and pressed in order to cover the grain deposited therein. Forholding the press roller under tension I provide the frame I with across bar I5 having an aperture through which extends a curved bolt Lwhich is provided with a threaded portion L on wlnch is mounted a nut Lforming a stop for limiting the movement of the frame toward the boot.The bolt L is carried by the plate G, and is rovided with a threaded endL on whic is mounted a ring nut L adapted to engage the outer endportion of the coiledspringlVI which surrounds the bolt between the nutand cross bar K as clearly shownin Fig. 2.

which may of the ordinary construction, and preferably formed of fabricand rubher, and secured on the lower endof said tube is adis'tributer Owhich scatters the grain passing through the tube into the boot' in sucha manner that the grain 'will be thoroughly scattered before it leavesthe boot, and deposited into the furrow in order to prevent the grainfrom becoming bunched. The distributer -O is formed of a blank of sheetmetal cut in the shape shown in Fig. 7, and comprises a central circularportion 0' and end oblong portions 0 which are provided with openings 0-and tongues 0* which are ndaplted to be forced through the openings intot e tube and clenched as shown in Fig. 6 in order to secure the same inposition on the end of the tube. The circular portion 0 is bent so as toform a substan tially inverted V in order to deflect the grain out toeach side so that when the grain leaves the tube it will be scatteredWithin the boot.

What I claim is:-

1. A grain drill comprising a boot having a shovel at its forward end ofa greater Width than the boot, a series of deflectors arranged withinthe boot, and a grain tube extending into said boot havinga distributorat its lower end.

2. A grain drill comprising a boot, a distributer extending into saidboot, deflectors arranged Within the boot and below the plane of thedistributer, and a shovel secured upon the frontside of the boot, thesaid shovel and the deflectors being held in place by common securingmeans.

3. A device of the kind described com
